routledge bore in a rem 514 smoothbore 22

[jeeper1]

What is the reasoning behind the increased diameters of the bore?

[fyrepowrx]

larger bore diameter = shorter shot column, and less shot in contact with bore, which in theory means fewer deformed pellets to go zinging off where you dont want them to go.

I have always wanted to try one of those smooth bore guns, i like the old Remington 500 series of bolt .22's and have bought several, when my grandfather started teaching me shoot 35 years ago it was a 514 Remington i learned on.

I suspected that was the reasoning behind the stepped up diameters. It's that before I bought this rifle I had never heard of that setup. While researching the rifle all I found was a closed auction from january 2005.

My rifle looks like the one pictured in the auction except it is rust free.
